WEE OOILING AND CLAMPING DEVIOE.

Specification of Letters Patent.

Patented Oct. 2, 1917.

To all whom it may concern:

Be it known that I, JULIAN J. Nmrsnn, a citizen of the United States, residin at Chlcago, in the county of Cook and tate of Illinois, have invented certain new and useful Improvements in Wire Coiling and Clampinfi Devices,- of which the following is a spec' ation.

My invention relates to means for coiling a w1re around the shank of a wire clam ing member'and subseq uentl clamping t e wire in place by operation 0% said clamping member. I

One of the objects of my invention is to provide a wire coiling device for coilin the wire about a wire clamping screw and w ch is adaptable for use with standard screws without modification or change of any kind in the character of the screw.

Another object of my invention is to provide a wire coiling member adapted to be rotated about the threaded clamping member and which is primarily operated to coil the wireabout the shank of the clamping member, such as a screw, prior to the subsequent rotation of the screw to clamp the wire which is permanently associated with the screw and which may be rotatable'independently thereof.

Other and further objects of my invention will become readil apparent to persons skilled in the ,art om a consideration of the following description when taken in conjunction with the drawings, wherein Figure 1 is a plan view of one form of my wire clamping and binding device.

Fig. 2 is a section on line 22 of Fig. 1.

n all the views the same reference char.- actors are employed to indicate the same parts.

The embodiment of my invention is of the same general character as that disclosed in the application of John Cuthbert for wire coiling and clamping devices Serial No. 35,064 filed June 19th, 1915. In the aforesaid application the operation of coiliiig the wire about the shank of the associated clampin'gmember is accomplished by rotation of the coiling and clamping member prior to its clamping action. In my invention the coiling member is a part separate from the clampin member, and may be made rotatable in ependently of the clamping member.

In the drawings representing my invention I have shown two forms which my in vention ma take, merely to more clearly exemplify the fact that it is not to be confined to a single showing. It is capable, however, of further variatmn, not necessary to be shown and is limited only by the scope of the appended claims.

. 10 is a ody or base, which may be of insulating material, such as a block of porcelain or the like, to which a wire binding screw is to be attached. 11 is an mteriorly screw threaded sleeve, having'a terminal fla held in place by a screw 12 and was er 13 taking throu h an orifice 14:, in the opposite side of the ase. An enlarged washer 15' ma if desired, underlie the flange of the s eeve 11. The flange 11 and the washer 15 are perforated near the axis of the clamping member, as at 16, to insert the conducting wire 17 prior to being clamped. A clampin screw 18 is insertible in the screw threads sleeve '11 and is the means for'clamping the wire 17 between the head of the. screw and the flange of the sleeve 11. Threaded over the screw 18is a separable clamping member 19 having oppositely downturned flanges 20 providing wire-en ging shoulders 21. The flange 20 should e preferably of length less than the diameter of the wire to be clam ed. The wire coiling member 19 is centre ly perforated, as at 22, throu h which perforation the screw 18 passes; "Fhe clamping member is provided with means for engaging the device used to rotate the screw such, for instance, as one or more laterally extending fingers 23. Two such fingers are shown on opposite sides of the axis of the perforations 22-. After the member 19 has been threaded over the clamping screw 18 the fingers 23 are bent up on either side of the screw slot..

To operate the devices shown in Figs. 1 to 5 inclusive the wire 17 is first threaded through the perforation of the block 10 and through the perforations 16 made through the flange 11 and the washer 15, which perforations in'the said devices register, and the end of the wire is extended be ond the shank of the screw 18 suflicient y to be coiled about said shank. At this time the screw 18 may be some distance out of the threaded sleeve 11 so as to permit the wire 17 to pass under the coiling member 19. A screw driver is now inserted in the slot 24 of the screw 18 and between the fingers 23 of the coilin member on either side of the said slot an the screw and coiling device are thereby rotated. The contact of the screw driver, when it is sufliciently wide to span the slot 24 and engage the fingers 23, rotates the coiling member 19 that coils the wire around the shank. The shoulders 20, one on either side of the shank of the screw, serve to hold the coil of the wire adjacent the shank and prevents its movement from the position in which it has been coiled. A narrower screw driver may now be inserted in the slot 24 of the screw, so that it will not touch the fingers 23 and the screw may be further rotated independently of the soiling member to clamp the wire in posi- In the modified device shown in Figs. 6, 7 and 8, the clamping member is not necessarlly pro 'ded with laterally extending fingers 23, r engagement with the screw drlver to rotate sa1d coiling member, but instead thereof sleeve 23' is placed upon the shank of the screw driver 25 and is axially movable thereon, being limited onl by the pm 26 which Iplrojects laterally fi om the screw driver. I e sleeve 23 is provided with a slot 27 termihatin in notches 28 at each end within which "t e pin 26 may be contained when moved out of the slot 27. The lower notch 28 is preferably somewhat larger than the upper one and when the sleeve is raised so t at the pin is c ntained in the lower notch 28, the sleeve 2. is held above the screw driver oint 29. The sleeve 23 is cut away on eit or side on its lower end, as at 30, to provide a bifurcated end consisting of two points 31. Whenthe sleeve 23 isin the position shown in Fig. 6, the points 31 engage opposite sides of the wire coiling member 19 and u on rotatlon of the screw driver 25 the coillng member 19 enages the wire 17 and coils it around the shank of the screw 18. After the wire has thus been coiled in proper position, the sleeve 23 is raised on the shank of the screw driver 29, upon which it is freely movable, in an axial direction until the lower notch 28 engages the pin 26, on the screw driver and thereby the sleeve 23 is moved out of the wa of the point 29 of the screw driver and he (1 in position thereon, after which the screw 18 may be rotated to wire clam ing position, by means of the point 290 the screw driver entering the slot 24, independently of the wire coiling device.

Either form of the wire coilin member 19 or any equivalent thereof may e placed upon any of the standard screws, such as screw 18, and used in the manner described.

Having described my invention, what I claim is:

1. The combination with a rotatable wire clamping member, of a wire coiling member detachably associated with the wire clamping member and having an abutment for engagement with a rotating tool, and a wire engaging and coiling projection thereon.
